A nun walks her dog past Haitian immigrants at the Nossa Senhora da Paz Catholic church, where the immigrants are staying in a shelter, in the Glicerio neighborhood of Sao Paulo April 28, 2014. Two years ago, the Brazil government announced the creation of a humanitarian visa that would be exclusively issued to Haitian refugees after the devastating 2010 earthquake on the island. Around 800 Haitians immigrants have arrived in the last two weeks in Sao Paulo looking for work from the northern state of Acre. Picture taken April 28, 2014.
